Also, Mr Stewart said he and Queensland Police Union president Ian Leavers met with leaders in the Muslim community and told them police would go out of their way to ensure their safety.

"Whilst it is our strong view that this is not religiously based or culturally based, the perception may be in some quarters that the Muslim community have some ties to the perpetrators of some of these crimes," he said.

"They are simply people who have no respect for any of us or for any particular religion or religious group."

Newman approves $1.5 million extra for QPS

Queensland Premier Campbell Newman today revealed police had been given another $1.5 million in funding, including $1 million for overtime in the next 60 days.

Mr Newman said the extra money was approved on Sunday in response to a request from Mr Stewart.

"That's $1 million to ensure we have the police presence on our streets at the time that we need it in the run up to the G20, during a period of uncertainty and community concern, where we need to really send a strong message to people that the Government and Queensland Police Service are doing everything they can to protect the people of this state," Mr Newman said.

Mr Stewart said the money would be used to employ four more Muslim police liaison officers.

Mr Leavers, who appeared alongside Mr Stewart at a media conference, said they were also discussing ways to increase the safety of officers.

"Police are concerned right across the state and we've been inundated with queries," Mr Leavers said.

"I want everything available for police to be able to protect them."
